Algebra.Com's Answer #183816 by drk(1908) ![]() You can put this solution on YOUR website! First we need a definition: Supplementary angles are two angles that add to 180 degrees. The key part is \"ratio\". When they say this place an x next to each number and apply the appropriate definition, in this case supplementary angles. So, we have\r \n" ); document.write( "\n" ); document.write( "4x + 5x = 180 \n" ); document.write( "9x = 180 \n" ); document.write( "x = 20.\r \n" ); document.write( "\n" ); document.write( "This is your multiplier. So the smaller angle is 4x = 80. \n" ); document.write( " |
